History of the Animal Science Industry
2
Early Domestication
  • Humans began domesticating animals more than
    10,000 years ago beginning with dogs.
  • Ruminants (cattle, sheep and goats) were the
    first food animals to be domesticated followed by
    pigs, possibly to dispose of table scraps and
    waste products.
  • Horses and cattle were domesticated primarily for
    transportation and draft work purposes.
  • Early people found animals that form large herds
    or flocks and eat a wide variety of feeds are
    easier to domesticate.

3
Early Domestication
  • Domestication involves more than simply taming.
    Animals are considered to be domesticated when
  • they are kept for a distinct purpose
  • humans control their breeding
  • their survival depends on humans
  • they develop traits that are not found in the
    wild

4
Domestication
  • Domestication allowed humans to
  • Contain animals with the right temperament
  • Have a steady food supply
  • Use animals for companionship, religious purposes
    and draft work
  • In return, the animals received protection and a
    constant food supply.
  • Selective breeding occurred as humans got rid of
    animals with undesirable traits, not allowing
    them to reproduce.

5
Which of these animals was domesticated first?
  • List them in the order you think they were
    domesticated on your notes page.
  • Cattle? Horses?
  • Goats? Chickens?
  • Pigs? Turkeys?
  • Sheep?
  • Whats your guess?

6
Sheep Domesticated 11,000-15,000 years ago
  • Domesticated in the mountains of Southeast Europe
    and Central/Southwest Asia. These areas include
    the countries of
  • Greece, Kazakhstan, Turkey, Hungary,
    Uzbekistan, Syria Yugoslavia, Turkmenistan,
    Iraq , Romania, Tajikistan Bulgaria, Afghanistan
    and Iran
  • Favorable because of their wool and meat for
    which they are still used and bred today.
  • Because of selective breeding for traits and
    other results of domestication, sheep are the
    only species of livestock that would be unable to
    return to the wild.

7
Cattle Domesticated 10,000-15,000 years ago
  • Domesticated near the boundary of Europe and Asia
    and/or Southwest Asia
  • This area includes the countries of Russia,
    Turkey, Ukraine, Syria, Moldavia, Turkmenistan,
    Iran, Iraq
  • In the beginning, cattle were used mainly for
    meat, milk and labor but eventually were replaced
    by horses in most of the draft work.

8
Horses Domesticated approx. 5,000 years ago
  • Horses were domesticated in Eastern Europe and
    Western Asia. This area includes the countries of
    Mongolia and Siberia.
  • Originally, horses were used for meat and milk,
    but eventually became useful as pack and draft
    animals.

9
Pigs Domesticated 5,000 - 9,000 years ago
  • Pigs were first domesticated in the Middle East
    (Mesopotamia) in countries such as Syria, Iraq
    and Turkey and then spread across Asia, Europe
    and Africa.
  • Pigs were utilized more in settled farming
    communities than in nomadic groups because they
    are difficult to move for long distances.

10
Animal Domestication
  • Goats
  • The goat was among the earliest animals to be
    domesticated, around 6000 - 7000 B.C. in Western
    Asia.
  • The goat could easily revert to its wild state.
  • Chickens
  • Chickens were known in China more than 3,400
    years ago and also in Southeast Asia (China,
    Laos, Vietnam, Cambodia, Thailand, Indonesia,
    Malaysia, Philippines, Burma)
  • Turkeys
  • The turkey is the only North American domestic
    animal and was domesticated in middle North
    America.

11
Use the information . . .
  • Use the notes we just took to draw a simple
    timeline on your worksheet illustrating the order
    in which animals were domesticated.
  • It might look something like this.

Sheep 11,000-15,000 years ago
Cattle 10,000-15,000 years ago
Goats 6,000-7,000 years ago
Pigs 5,000-9,000 years ago
Present
Chickens 3,400 years ago
Horses 5,000 years ago

What is animal science?
  • Animal husbandry is the art of working with farm
    animals.
  • Animal science is the scientific study of farm
    animals.
  • Biology is the study of life that seeks to
    provide an understanding of the natural world.

14
History of Animal Agriculture in the United States
  • Columbus brought livestock to the West Indies
  • Cortez brought cattle and sheep to Mexico
  • 1539 DeSoto brought horses and hogs to Florida
  • 1641 William Pynchon, Massachusetts, was first
    meat
  • packer exporting salt pork
  • 1760 Robert Bakewell, England, began breeding
  • animals for a purpose, created
    different types.

15
History of Animal Ag in U.S.
  • 1861-1865 Changes occurred during the Civil War
  • Railroads decreased need for horses and mules and
    for stock to be raised where they are consumed
  • Refrigeration in box cars allowed shipping of
    carcasses to population centers
  • Now animals could be raised in one place, sold at
    another and consumed at yet another.
  • Change in tastes beef became most popular.
  • Before the war, pork was the most popular meat
    (mainly due to ease of storage), but beef became
    the most popular meat after the war because of
    refrigeration.

16
History of Animal Ag in U.S.
  • 1862 Land Grant Act provides public
    lands for universities to teach agriculture
  • 1872 Hatch Act establishes experiment stations
  • 1914 Smith Lever Act establishes cooperative
    extension service

17
Animal Contributions to Society
  • Food
  • Mutton and chevon are eaten by more people
    than any other meat
  • Beef is eaten in larger quantities than any other
    meat.
  • Certain religions restrict beef and pork
    consumption
  • Hindus do not eat beef.
  • Muslim, Hind, and Orthodox Jews do not eat pork
  • Many people eat horsemeat
  • Goats, ewes, cattle, mares, sows, llamas, camels,
    reindeer and yaks provide milk and milk products.

18
Animal Contributions to Society
  • Clothing
  • Wool, hair, hides (leather), and pelts have
    commonly been used for clothing.
  • Even today, in more than 100 countries, ruminant
    fibers such as hair and wool are used in the
    manufacture of clothing, bedding, housing and
    carpets.

19
Animal Contributions to Society
  • Shelter
  • Hair and hides provide material for shelter. For
    example, hides are used in teepees, while hair is
    used in plaster (horsehair plaster).
  • Tools
  • Early man relied on bones and hides for tools.
  • Utensils
  • Bladders, horns, catgut and dynamite are animal
    products that are commonly used.
  • Personal Items
  • Humans use animal products or by-products for
    jewelry and perfume.

20
Animal Contributions to Society
  • Power
  • Animals have always been important throughout
    history for draft work, packing and transporting
    humans. In the 1920s, more than 25 million horses
    were used primarily for draft purposes.
  • Today, in developing countries, animals provide
    as much as 99 of the power used in agriculture
    while 20 of the world's populations depend on
    animals for moving goods.
  • India has more than 200 million cattle and
    buffalo, but because cattle are sacred in India,
    they are not slaughtered for meat. These animals
    are used to provide power for field work.

21
Animal Contributions to Society
  • War
  • Animals were used in war for transportation and
    power
  • Religion
  • Some societies worship animals.
  • Recreation
  • Companionship and hobbies or sports such as
    horseback riding
  • Health
  • Laboratory animals are commonly used for
    research.
  • Miniature pigs have been used in laboratory
    research because they closely resemble humans in
    their pulmonary, cardiac, dental and even
    pre-natal brain development.
  • Cattle and sheep have been used to test
    artificial organs before use in humans.
  • Humans also use animal products and by-products
    in pharmaceuticals.
